You can use the MATLAB® Unit Test framework to run tests authored in Simulink® Test™. Using the MATLAB Unit Test framework:
Allows you to execute model tests together with MATLAB Unit Test scripts, functions, and classes.
Enables model and code testing using the same framework.
Enables integration with continuous integration (CI) systems, such as Jenkins™.
To run tests with MATLAB Unit Test:
TestSuite from the
Create plugin objects to customize the
TestRunner. For example:
Add the plugins to the
When running tests using MATLAB Unit Test, consider the following:
If you disable a test in the Test Manager, the test is filtered using MATLAB Unit Test, and the result reflects a failed assumption.
MATLAB Unit Test has analogous properties to the functionality in Simulink Test. For example,
If the test case contains iterations, the MATLAB Unit Test contains parameterizations.
If the test file or test suite contains callbacks, the MATLAB Unit Test contains one or more callbacks fixtures.
parameterization details correspond to properties of the iteration.

Iteration type: Scripted
Iteration type: Table

Fixtures depend on callbacks contained in the test file. Fixtures do not include test case callbacks, which are executed with the test case itself.

This example shows how to create and run a basic MATLAB® Unit Test for a test file created in Simulink® Test™. You create a test suite, run the test, and display the diagnostic report.
Before running this example, temporarily disable warnings that result from verification failures.
warning off Stateflow:Runtime:TestVerificationFailed; warning off Stateflow:cdr:VerifyDangerousComparison;
1. Author a test file in the Test Manager, or start with a preexisting test file. For this example,
AutopilotTestFile tests a component of an autopilot system against several requirements, using
2. Create a
TestSuite from the test file.
apsuite = testsuite('AutopilotTestFile.mldatx');
3. Run the test, creating a
TestResult object. The command window returns warnings from the
verify statement failures.
apresults = run(apsuite);
